Another patch w/ Tahm Kench ignored entirely

Currently, Tahm Kench sits at 46.23% and 45.37% winrate support and top respectively. He hasn't even approached 50% (49.32% and 48.72%) since patch 6.22, and that was only for one patch. Even pros, per Probuilds, only hover at 50%. According to OP.GG, sorted by the last 7 days, it's not until you reach Master and Challenger that he surpasses 50%, and that's with only somewhere in the ballpark of 100 matches played, meaning not much of a sample size.

On top of that, he's so underplayed that Champion.GG cannot even populate a most common or highest winrate build for top lane. OP.GG is much the same, with the most common runes and mastery pages being used by something like a couple dozen people, according to the site.

Then there's the matter of his bugs and matters needing fixed. His W minion spit doesn't always apply splash damage (seems to be a result of the minion being too low prior to W). His W also needs a complete overhaul, allowing for use with target champions only (if I eat one more minion instead of an ally/even because it happened to be there at the wrong time), and with improved prioritization (yes, I wanted to eat full HP ally instead of low, 3 stack enemy). That's not including the many other bugs that pop up, like inactive Heimer turrets becoming temporarily invulnerable if eaten, the various ways he can eat buffs (ex. try to eat enemy standing next to one without 3 stacks), etc.

Yet, in spite of all this, he seems to have become even more forgotten about than Aatrox, for instance. At least Riot admitted to Aatrox needing attention. Tahm Kench, on the other hand, hasn't received any balance changes, bug fixes, or been discussed since the work done on him on patch 6.13.

Needless to say, this radio silence is becoming an endless source of frustration for me, a Tahm Kench one trick. Can I at least get some confirmation he's being looked at for something?
